missing Mime-Version and format=flowed

[Reiner Steib <4.uce.03.r.s@nurfuerspam.de>]

Hi,

Gnus displays garbage when viewing the following messages:

,----(1)
| Subject: Bitte um Rat: "Symbol's function definition is void: subject"
| Newsgroups: de.comm.software.gnus
| Organization: Newsoffice.de - http://www.newsoffice.de
| Date: Tue, 03 Aug 2004 08:32:11 +0200

| Content-Type: text/plain; charset=utf-8; format=flowed
| User-Agent: Newsoffice.de - based on NewsPortal
`----

==> Gnus doesn't decode the UTF-8 characters correctly.

==> The Latin-1 characters are displayed as eight-bit-graphic.

Further tests (those messages have been posted in <nntp://gmane.test>)
showed that Gnus displays message no. (1) correctly if a Mime-Version
header is added or if "format=flowed" is stripped:

[ for i in {4,5,6,8}-v98ycvrqoe.fsf@marauder.physik.uni-ulm.de; do
    echo "# <news:$i>"
    echo head "<$i>"|nc -w1 news.gmane.org nntp|grep -ie '^Content-\|^Mime-'
  done ]

# <news:4-v98ycvrqoe.fsf@marauder.physik.uni-ulm.de>
Mime-Version: 1.0
Content-Type: text/plain; charset=utf-8; format=flowed
Content-Transfer-Encoding: 8bit

==> Displayed correctly in Gnus.

# <news:5-v98ycvrqoe.fsf@marauder.physik.uni-ulm.de>
Mime-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit

==> Displayed correctly in Gnus.

# <news:6-v98ycvrqoe.fsf@marauder.physik.uni-ulm.de>
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit

==> Displayed correctly in Gnus.

# <news:8-v98ycvrqoe.fsf@marauder.physik.uni-ulm.de>
Content-Type: text/plain; charset=utf-8; format=flowed
Content-Transfer-Encoding: 8bit

==> Displays garbage as message (1). 


As the Mime-Version header is required (IIRC), it's a bug in
Newsportal, I think.  But maybe we could make Gnus more tolerant.

It's quite surprising, that the more tolerant decoding in Gnus doesn't
allow "format=flowed".

Bye, Reiner.
